What does it mean to be a toxic person?

[Ronshell]

Are you keeping your partner from things that make them happy? Do you tend to boss around your partner, making him/her do things according to your preference? When your partner wanted to do things he/she enjoys without you (because your partner knows you don't like it anyway), do you throw a tantrum just to keep him out of it? Do you think that your partner thinks the way that you do? or at least that's what you are trying to convince yourself? We could go on and on and on. Most of us don't even realize it, if unnoticed, we can become a toxin to the person we love dearly; and we don't want that to happen, do we?
